cifs: add revalidation on FSCTL failure in smb2_duplicate_extents()
smb2_duplicate_extents() has no handling for
FSCTL_DUPLICATE_EXTENTS_TO_FILE failure: when the FSCTL fails, local
inode metadata may be stale from the pre-extension or from concurrent
remote writes, but is never refreshed.
Force revalidation on FSCTL failure and use i_size_read() for the
pre-extension check.
Fixes: cfc63fc8126a ("smb3: fix cached file size problems in duplicate extents (reflink)")
